lt is the primary object of the present in,

vention to provide a toilet suited for instal- 5 lation in homes andbuildings situated in rural districts where sewerage systems are notpresent.

A further object of the invention is to providea waterless, sewerless,odorless and 10 sanitary toilet.

A further object of the invention is to provide a toilet adapted tobecharged with chemicals to destroy all bacteriaand germ life, renderingthe device safe andy sanitary,

15 -yet very economical.

always be caused to seat very tightly, evenY after the valve Vfacing orpackinghas become worn.

A further object of the invention is to provide acliemical toiletprovided with an agitator operatively connected with the seat so as tobe automatically operated when the seat is moved. i

A. further object of the invention is to provide a device of the classdescribed equipped with a ventilating system.

A further object of the invention is to provide a chamical toilet whichis of simple construction, is inexpensive to manufacture, is -strong anddurable, and is well adapted for Jthe purposes described.

With the above and other objects in view, the invention consists of theimproved toilet, and its parts and combinations as set forth intheclaim, and all equivalents thereof.

Y ln the accompanying drawings, in which the saine reference charactersindicate the same parts in all of the views:

Fig. l is a vertical sectional view of the improved chemical toilet;

v taken online '2-2 ofvillig. l', and on a larger scale; and Y.

" Fig. 3 is an enlarged detail view, partly in section, showingthe'valveand the valve operating mechanism.' f

Referring now" more particularly to theV Y drawings, it will appear thatthe numeral 5 being adapted vtonextend above a floork line. lAn.annularangleiron member 7 is riveted externally to trie lower portion of thetankniember 6 and the'horizonta'l flange thereof is adapted to rest onthe floor 8, as shown.

An annular anglek iron member 9 is seupper endA portion of thc tank@with tlieliorizontal flange projecting exteriorly, and'one ormorebrackets` l0 are lsecured to said angle iron member and said bracketscarry pivotal hinges 1l and l2 which are secured to a seat 13 and a.coverl4, respectively. The bracket is formed withl an Vangular portionl0 forming va stop for the hinge l2 when'the cover is in'open position,as shown in dotted lines in Fig. l. l.

A paddle shapedagitator l5, formed with apertures l5', is pivotallyconnected at its inner end portion with a bracket 16 secured to theinner wall of the/lowerportion of the tank. 5, and the lower portion ofan elongated operating rod 17 is pivotally conk nected, as at 18, with amedial portion of the agitator. vThe upper end portion of said rodis'bent slightly and is pivotally connected with a bracket 19 dependingfrom the cover le.V By this construction, when the cover is raised orlowered, the agitator is automati bottoni 2O and extending into saidopeningis a as at 23, to receive thereon an elbow section 2li. .Theinner surface of the inner end portion of'said coupling is beveled, asat 25, to

tightly receive atapered valve member 26.

a depending coupling externally threaded,

Said tapered valve member seats as shown in Fig. 3, and is secured to anupper valve plate 27 by means of a screw 28. A sealing disc 29 ofleather is interposed between the valve members 26 and 27 and covers theinner end portion of the coupling 22. Y r)lie upper valve plate isprovided with an apertured boss 27 into which extendsthe lower endportion of a valve rod or stem 30; rl`he boss porl tion 27 is providedwith a pair of opposed pins 31 which enter an annular recess 30l` inthelower portion of the stem 30. By thisL means, the stem is preventedfrom withdrawal frointhe valve plate boss, bnt the valve and steni aremovable with respect to each other and dueto the fact that the conectionis not rigid, the valve willalways accurately seat.

Secured to the inner sidewall ofthe tank 6, near the upper end thereof,is a bracket 32 having anupper right angular plate portion 33 and alower` right angular plate portion 34. The lower plate portion 34 is`formed with a circular opening 35 having a communicating slot 36, whilethe upper plate portion 33 is formed with a depending apen tured lug 37havingfa slot 38 communicating with the aperture or bore therethrough.Also,k

the bottom portion of thelug 37 is formed with a camsurface 39.

As shown clearly inthe drawings, the valve rod or stem 3O-eX`tendsvertically upwardly within the tanksadja'cent the side wallsY thereofand through the apertures `of the bracket plate 34 andthe lug 37. Theupper end portion ofthe rod is formed with a squared portion 40 topermit the insertion of a keytheieon for turning the rod and operatingVthe valve. Also the rod is provided with a pair of projecting pins 4land 42, which, in the normal position of the valve and valve rod, are soarranged that the pin :4l is Vdisposed imniediatelybelow the camsurface39 of the lug 37, while the pin 42 is slightly above the plate 34.

The toilet is adapted for installation in any convenient part of abuilding with the lower tank 5 extended below the floor line. vrIheelbow 24v connects with a drain pipe which extends to a suitablecontainer located eX- teriorly of the building, as a dry well or bar?rel.l The lower portion of the tank is adapted to contain suitablechemieals'to destroy bacteria and germ life, and periodically the valve26 is opened, as will be explained in detail, to drain the tank, and afresh charge of chemicals can thereafter'be` added. An elbowedVentilating pipe 43 extendingfroinv an opening in the rear of the upperportion of the tank 6 is further provided and said pipe mayV extendVthrough the roof of the building.

To vseat or close the valve, a'key is applied to the squared upper endportion of the valve rod 30. The key and rod are turned ina Vclockwisedirection iny Fig. 3 and the contact between the pin 4l and the camsurface 39 of the lug 37 will cause the rod to be forcedk downwardly.The pressure will tightly seat the tapered valve portion 26 and also theintermediate leather member will be coinpressed to tiO'htly seal theopening. To open the valve, the key and rod are turned in a reversedirection until the pin4l is` in register -withthe slot 38.17 Then',therodfand valve may be lifted vertically upwardly. lf theseen that theimproved' chemical toilet is of simple and novel' construction, andI iswell adapted for the purposes described;

VTWhat l claim as my invention is: Y Ina tank havinga drain opening, a"valve for said opening, said valvek having a lower tapered 'valve plate,an upper cuppedvalve 'j ilate, and an Vintermediate compressible layer,a valve rod loosely secured at its lower end portion in said cuppedvalve plate, a brackety secured toV said tank, said bracket having aslotted boss portion'through which the rod inovably extends, the lowersurface of Vsaid boss being eccentrically curved to form a cam surface,and a pin projecting laterallyfrom said rod for engagement with said camsurface,said pin also being registrable with said bloss slot-to permit alifting` movement of the valve rod.

ln testimony whereof, I afliX inv signature.
